VLSI Applications form the key to many emerging systems of modern technology. Today there are several applications where FPGAs can provide better solutions than ASICs and conventional microprocessors. With the advent of FPGAs we have entered the era of reconfigurable computing. FPGAs act as a sort of system-level silicon super-glue, sitting at the periphery of the circuit board making anything to connect to anything else, so that we could adapt on the fly and change our design to leverage any new, improved component without having to abandon the rest of the design.
